We evaluated the possible clinical application of Non HDL-cholesterol and triglyceride to HDL-cholesterol ratio as a metabolic syndrome predictor for the elderly in Korea. 1,543 elderly persons aged 65 years or older who visited the health examination center of Gyeonggi Regional General Hospital from January 2015 to December 2017 and had a health checkup were enrolled in this study. Metabolic syndrome was diagnosed based on the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) standards. Abdominal obesity was assessed by the Asia-Pacific standards presented at the World Health Organization (WHO) West Pacific Region. Non-HDL-cholesterol was calculated as the difference between total cholesterol and HDL-cholesterol. The metabolic syndrome predictive power was higher for triglyceride to HDL-cholesterol ratio than for Non HDL-cholesterol. After correcting for related factors, triglyceride to HDL-cholesterol ratio was higher in the $4^{th}$ quartile, which had a higher risk of developing metabolic syndrome, than in the $1^{st}$ quartile. The optimal cutoff value for the triglyceride to HDL-cholesterol ratio that predicts the onset of metabolic syndrome was 2.8. triglyceride to HDL-cholesterol ratio can be a simple and practical indicator of the risk of metabolic syndrome.

This study interprets the corporate social responsibility and its management through analysis of philosophical view of Mozi(墨子). Mozi was a chinese philosopher during the Hundred Schools of Thought period. He advocated Universal love(兼愛), which stresses that people should care for everyone equally. This principle is in accord with the sustainable management strategy for global market environments. The realization of the value that the company pursues in the rapid growth of such enterprises is an important issue. The pursuit of corporate value in its own interest under the rapidly changing business environment is perceived very negative. And it has demanded a different philosophy as a new management philosophy. The philosophical strategies of these companies were centered around the core philosophy of the ancient Chinese philosopher, Mozi. It is not merely an outcome approach as the act or moral principle but the inner motive to love each other and the principle of sharing the profits of each other. In order to pursue the sustainable value of the enterprise, We would like to suggest a way to pursue the existing absolute value, and to suggest a philosophical strategy based on the philosophy of Mozi.

This study examined the control effects of amino acid biochemical agent extracted from chicken feathers on Meloidogyne incognita for the purpose of developing an environmentally friendly nematicidal agent that can replace chemical control of root-knot nematodes (RKN). We investigated the lethal effects of J2 juveniles for 19 types of commercial amino acids. As a result, five kinds of amino acids (L-asparagine, L-aspartic acid, L-methionine, L-tyrosine, L-cysteine) showed mortality rate of more than 50% at a concentration of 50 mM. L-asparagine showed the highest mortality rate at 94%. We also investigated the lethal effect of J2 juveniles and suppressive effects of egg hatching by feather amino acids (FAA) biochemical agent. It showed that the mortality rate of J2 juveniles was more than 80% and suppression rate of egg hatching was 74% at 1/50 concentrations of FAA. As a result of conducting a tomato pot culture experiment for 60 days after treating 1/50 concentrations of FAA biochemical agent in rhizosphere soil, it showed that the control effects were 63% of juveniles density in the soil, 59% of egg mass and 61% of root gall index, respectively. Based on the above results, it is considered that the FAA biochemical agent extracted from chicken feathers can be used as an environmentally friendly nematicidal agent of RKN.

Seed morphology in the subtribe Agrimoniinae (Rosaceae) was examined using scanning electron microscopy to identify distinct characters and evaluate their evolution in a phylogenetic framework for five genera in the subtribe: Agrimonia L., Aremonia Neck. ex Nestl., Hagenia J.F. Gmel., Leucosidea Eckl. & Zeyh., and Spenceria Trimen. All genera have one or two mature achenes in a fruiting hypanthium. In the seed coats, the cell shape, size, wall features, and sculpturing vary across genera. Of most significance is the presence of papillae structures in both Agrimonia and Aremonia. Through the mapping of papillae features onto phylogenetic trees, either one or two changes in seed coats are hypothesized. The phylogenetic tree inferred from four nuclear and six chloroplast regions of sequence data suggests that at least two steps of papillae sculpturing on seed coats are required. On the other hand, in the phylogenetic tree of a low-copy nuclear gene, one independent evolutionary step is postulated to explain the current character states. In the latter hypothesis, the seed coat sculpturing also supports a monophyletic relationship for cosmopolitan Agrimonia and European endemic Aremonia. The seed coat sculpturing provides valuable information for inferring phylogenetic relationships at the generic level in the subtribe Agrimoniinae.

This study was intended to develop a value-added and functional sauce with addition of Chungkukjang powder. This study was conducted as the following procedure. 10%, 20%, 30%, and 40% of Chungkukjang powder was respectively added to make different Bechamel sauces. And then, physical testing (moisture, color value, viscosity, salinity, spreadability and pH) and sensory testing (a quantitative descriptive analysis and an acceptance test) were performed. After that, the correlation between the physical testing and the sensory testing was investigated to choose an optimal mixture ratio. The study results are presented as follows. As the addition percentage of Chungkukjang powder increased, a-value, b-value, salinity, spreadability, and pH significantly increased (p<0.001), but moisture content, L-value and viscosity decreased. The QDA result indicated that, regarding color intensity(5.89), Chungkukjang flavor(5.32) and Chungkukjang taste(6.26), the 40% addition group had the highest value, and that, regarding thickness(6.42), milk flavor(5.00), oily taste(5.21), mouth feel(5.32), the control group had the highest value. As a result, as the addition percentage of Chungkukjang powder increased, color intensity, Chungkukjang flavor, and Chungkukjang taste increased, but thickness, milk flavor, oily taste, and mouth feel decreased. According to the result of acceptance test, the 20% addition group had the highest value in terms of appearance, flavor, taste, glossy and overall acceptance. As shown earlier, it is considered that proper addition of Chungkukjang powder positively affects the overall acceptance, and that the 20% addition of Chungkukjang powder is most suitable to improve the sensory and physical quality-characteristics of Bechamel sauce.

Purpose - This study focuses on new type distribution channel that named as Omnichannel. Omnichannel is developed from Multichannel which is used in many distribution channels to buy or selling goods. Omnichannel basically needs an Information and Communications Technologies(ICT) to use, so researcher conduct a Technology Acceptance Model(TAM) to research model. Customer-brand relationship was used as dependent variable to focus on the role of Omnichannel. Research design, data, and methodology - The subject of this study is customer who purchase goods or service through omnichannel. Based on the literature from the preceding research analysis of TAM and customer-brand relationship, this study was constructed by the reference to previous studies, final research model design for figure out casual relationship among perceived ease of use, perceived usefulness, omnichannel use and customer-brand relationship. From 2016 February 3 to March 17, questionnaire survey targeted customers who use online and offline channels. 273 questionnaire survey had conducted, then, 252 survey data were available for empirical analysis. Researcher provide descriptive statistics for checking generality. Cronbach's alpha value was used to check the reliability of data. Exploratory factor analysis was used for purification of values and eigenvalue checking. After EFA, Confirmatory factor analysis was used to prepare structural equation modeling with executing structural equation modeling for confirming hypothesis which developed by researcher. Results - The main results of this empirical study are as follows. First, omnichannel's perceived ease of use has positive significant effect on perceived usefulness(estimate: 0.579). Moreover, omnichannel's perceived ease of use and perceived usefulness has positive significant effect on omnichannel use(estimate: 0.325,0.648). Second, using omnichannel has positive significant effect on brand-customer relationship(estimate: 0.521). Every hypothesis adopted as researcher designed. This study found out the intermediate relationship between perceived ease of use and omnichannel use by investigating hypothesis. Conclusions - Base on the empirical result, this study confirmed that TAM theory perceived has relation with omnichannel. First, factors of TAM has positive effect on omnichannel use, so it highlights the important role of customer based interface and usefulness. Especially, perceived usefulness has high indirect influence on ease of use and use of omnichannel. It seems that when customers try to decide use or not use omnichannel, customers focus on percept benefits from omnichannel. Thus, a provider should applicate attractive price table, accurate product or service information and high switching cost strategy to emphasize the usefulness of omnichannel. Second, using omnichannel enhances the relationship between customers and brand, because there are more time and frequency to serve customers. It is important because good relationship between customers can increase the future's financial performance through word of mouse, positive brand image and loyalty to brand or company. Finally, despite of empirical result and implications, this study has limitations. First, there are only a few previous studies about omnicahnnel, so literature reviews are restricted. While set up the factors which can affect the use of omnichannel, next study should be considered with broader theories or models(ex: contingency theory). Second, omnichannel has developed from multichannel, so comparative analysis is needed between these methods because there is a possibility about different forte character of each distribution system on customer's consuming patterns.

The purposes of this study were to identify the economic impacts of hosting a marine leisure event and thus provide fundamental information that helps maximize the economic value of the event. In order to accomplish such purposes, this study employed both an economic impact analysis(EIA) using regional input output model and a benefit and cost ratio analysis(BCR). In specific, this study utilized a survey method with a total of 300 event visitors and 70 foreign players and thus collected expenditure data from 110 valid out of town visitors and 58 foreign players. In addition, investment expenditure data were collected from the host city official. Accordingly, EIA and BCR indicated following findings. First, the total direct impact from both visitors and players was 387 million Won and this direct impact resulted in output multiplier effect(OME) of 591 million Won, value added multiplier effect(VAME) of 306 million Won and income multiplier effect(IME) of 252 million Won. Second, the host city's investment expenditure created OME, VAME and IME of 825, 432 and 366 million Won, respectively. In conclusion, these findings suggest that in order to effectively boost potential economic benefits, more marketing efforts development policies should be implemented for increasing the number of out of town visitors and the amount of spendings from them.
